As mentioned on the Zend Developer Zone, Jaybill McCarthy has written up a Blog post about ten of the PHP myths that are common on the web and the facts that dismiss them.

I am a PHP developer. Maybe even a halfway decent one. As such, I often find myself engaged in conversations on the subject of web application development in general and PHP in particular. I am continually flustered by the myths, half-truths and outright falsehoods that technical and non-technical people alike hold about this humble programming language.

Some of the points included in his "top ten" list are things like "PHP Encourages Sloppy Code", "PHP is slow because itâ€™s interpreted" and "PHP apps all look the same".
